That would just be too easy. But rest assured, whichever OS your allegiance lies with is supported by Etsy sellers Getting Weddy, who have both Mac and PC belt buckles starting from $15. Or further display your geek cred, and make your own. [Etsy via Technabob]
I am neither brave nor geeky enough to wear any of these belts, but if you are, then go grab these one-of-a kind belt buckles at Holly and PJ's Etsy shop Getting Weddy. The buckles – no belt included – range from $15 (USD) to $22.
